To all whom- 1' m .f1 y concer-n Be it known that l, WILLIAM El IilUzzY, a citizenvof the United States, residing at New York, in the county ofv N ew York and Stat-e of New York, have invented t .in new and useful Improvements in Caslrtvegisters, of which I declare the .following to be a full, clear, and exactJ description.

This invention relates to innfiroreinents in cash registers, and has more particular relation to improvements in mechanisms for automatically indicating the amount of change due the customer on ditiferent transactions.

The principal object of this invention is to provide a mechanism controlled by the operating devices which will indicate the amounts of change due according to the amounts received.

With this and incidental objects in view, the invention consists in certain novel features et construction and coi'nbination of parts, the essential elements ot which are `set dic-ato s with the change indicators and gearing f5.. same in section; Fig. 4v represents an enlarged detail view. partly in section, of the connections for driving the cent change indicator from the cent sale indicator; Fig. 5 represents an enlarged front elevation of the change indicator and its casing, theilatter being partly broken away g Fig. (3 represents a detail side elevation of the operating gearing for the machine; Fig. 7' represents a detail end elevation of the transfer locking disk and some of its cooperating parts for the change indicators; Fig. 8 represents a view similar to Fig: but looking in the opposite direction; Fig. 9 represents a detail end elevation of a ten tooth driving, disk connected to the cent sale indicator and its cooperatingl parts; and Fig. 10 represents a View similar to Fig. 9, but looking in the opposite direction. l

Described in general terms, the machine comprises a pluralityT Aoi keys arranged 'in banks and which determine the extent of movement imparted to the sale indicators by the operating mechanism. Geared to 'the sale indicators representing the penny banks is a change drum provided. with a plurality of the amount purchased. Characters representing such amounts are stamped upon the casing above said opening. The dollar drum is also provided with rows of numerals and is actuated in a similar manner by the dollar sale indicators and in addition is moved an extra space upon the move-ment ci the cent. drum, so as to correctly indicate the amount of change due. i

Detailed description of the part-s is as follows:

Sale inflicaors.-The mechanism oractuating these indicators is substantially the same as'shownrand described in the patent granted to Cleal and Reinhard, April 13, 1597 and numbered 580,378, and comprises a plurality of banks of select-ive or manipulative devices in the form of keys l, which control the ditferential movements of segments 2, onlyv one of which is shown, loosely mounted upon a shaft- 3, the latter being rocked by a link connection l through a rotary shaft 5 which is geared to the operating handle The segment- 3 of the penny bank meshes with a gear t which in turn engages with a pinion S secured to the penny sale indicator 9 through means of a sleeve 10, (see Fig. 3.) The dimes segment Z meshes with another gear "I which engages a pinion 11 secured to the limer end of a sleeve l2 and to which is attached the dimes indicatorl 13; The indicators 9 and 13 tra'nsfer their movements through gear-sli, shafts 15, pire ions 16, pinions 16 to indicators 17 and 18 respectively located at lthe other cnd of the machine and arranged to be read from the back of the same, while the indicators 9 and 13 are read from the front. The units of dollars indicator 19 arranged to lie-read from the back, is attached to one end of a sleeve 2O to which is also secured a. pinion 21, which u@ lars bank meshes with a gean? which in turn and dollar change indicators or drums. As1

engages a pinion 27 loosely. mounted upon the sleeve 20 near its outer end and has attachedthereto a gea-r 28 which engages a pinion 29 attached to a shaft 30 that also carries, .near the center of the'machine, a' similar pinion 31, which meshes with a gear 32 attached tothe side of the front tens of dollars indicator 33. `This indicator is attachedy to the inner end of a sleeve 34 to Awhich is also attached the backindicator 35 for the tens of dollars.

l Change ml-z'ca'wra-There are two of these indicators and they will be referred to in the description which follows as the cent previously' stated, these indicators which are controlled by the sale indicators are provided With a plurality of circular rows of numerals and each is arranged to be rotated 39 in reversed order from the numerical progression of said groups a number of units corresponding to that displayed by the sale indicators controlling it; that is, for every movement of the peny sale indicator the 35 cent change indicator will be moved one space and every movement of thevtens of cents sale indicator will rotate the cent change indicator ten spaces, so that if 55, for example, is displayed by the cent sale indicators, the change indicator will have been rotated ttyti\e spaces, thereby bringing into view the complements of any coin or coins above the amount displayed by the sale indicators, up to and including one dol- 'lar, that might be tendered in payment. The

v the cent change indicator dollar change indicator is controlled units and tens o'rn dollars a similar manner and in an extra movement upon by thc sale indicators in addition is given the movement of so as to properly indicate'the amount oi, change that is due, it an amount involving cents is to be subtracted from a bill or coin above a dollar.

Fastcned to the outer end of the sleeve 10 (see Figs. Il, 9 and 10) is a ten tooth wheel 36, the inner end ot said sleeve carrying the penny sale indicator 9. -For each unit of movement of said indicator a tooth of the wheel 2x6 engages the teeth oa-pinion 37 '15o and moves Athe latter one tooth in the 'direction of the arrow shown in Fig-.2. The pin' ion 37 is prercntcd from being. accidentally *raging a locking ring moved by a dish i 36 secured to the w eel which is Well known in the art. The pinionV 37 is mounted tated. by the. wheel 36 it will in turn rotate a disk 39loosely journaled on shaft 26 by .engaging teeth formed vupon an angular fiange portion 40 of said disk (See Fig. 2). These teeth form a gear wheel 41 which meshes with a portion l2 of a double pinion, the other portion -13 of said pinion meshing with a gear 44 formed upon the inner circumference ofV an'angular flange portion 45 of a disk JLG which is looselyinounted upon the sleeve 10. The outer circumference of the angular portion 45 .is provided with teeth forming a gear wheel 47, Which meshes with a similar wheel 18 secured to the out-er end of a sleeve 49 surrounding a shaft 50. The inner end of said sleeve is secured to one. of the side` walls of the centchange indicator 51 which is divided into one hundred sections.- The above described gearing is so proportioned, that for everV tenth of a revo- -lution of the penny indicator 9 the change indicator 51 will be revolved in the direction of the arrow, Fig. 2, one hundredth of a revolution.

As previously described the dime vindicator 13 is attached to the sleeve V12- to the outer end of which is secured apinion 52, which meshes with a pinion 53 mounted in thel end of adownwardly extending arm 54 secured to the shaft 26. The pinion 53v meshes with a gear wheel 54a formed internally upon a disk 55 loosely mounted upon the sleeve 12.. Attached to this disk .55 is an upwardly extending arm 56, which carries at its outer end the previous-ly described double pinion. The gear wheel 54a is twice the size of the pinion 52 secured to the sleeve 12, so that as the pinion 52 is rotated in the direction of the arrow, Fig. 2, one' tenth ot a revolution, the gear wheel 54a and disk will be rotatedin 'the opposite direction oneltwentieth of a revolution, but by means of the portion 42 of the double pinion rotating upon the gear wheel 41, the disk 16 carrying the gears 44 and 4T will be rotated twice as far, or one-tenth oi' a revolution which will be transferred to the cent change indicator through means of the gear i8 and sleeve 4).

1twill, of course, be understood-that if the cent. and dime indicators 9 and 13 rotate simultaneously, the gearing above described will so multiply the movement of the gear wheel 47 as lo produce an extent oI movement corresponding to the combined units of movement ot' said indicators and this movenient will be transmitted through the gearl vwheel i8 and the sleeve 49 to thepcnny change` indicator-51.

rfhe changev indicators as above nient are divided into a plurality ofcircular. rows of numerals whicii are arrangedto be eX- posed through openings 561 and 57 formed.

fthe amounts that might be tendered ink payment for goods purchased andv beneath' 'which the groups of numerals upon the change indicators rotate. Above-the openring 561 through which the numerals on the centchange indicator appear'are stamped Athe following figures: 100, 95, 90, 85, 80, 7 5,.

570, 60, 5o, 45, 35, 30', 2 5, 2o, 1 0 and 05, which represent some of the various amounts that might be. tendered where the amount purchased is' one dollar or` less. The groupof numerals beneaththe figures 100 runfrom 0 to 99 in reversed order to the direction of v@tation ofthe indicator as shown by the :arrow in Fig. 5.and make a complete circle vabout same;v the'group beneath'the figures 7 5 consist of numerals `from 1,v to 24 inclusive in addition tothe. 0 and are arranged lto be displayed during the movement of the indicator from the 'half to the three-quarters 25 ures 50, 25, 10 and 05 `consist respectively of' o'lfla revolution, the groups, beneath the ig' zeros and numerals 11 tb.49,1 to 24, 1 to 9 Tand 1 to 4 inclusive and are arranged to be ,displayed during the first fortynine, twenty-four, nine and four one-hundredths of a revolution of the indicator 51 respectively. The groups of numeralswhich ap- .pear below the .figures 20, 30, 35, 45, 60, 70, 80,85, 90 and 95v consist of numerals from 1 to 9r inclusive and are arranged to be displayed respectively during the movement of the change indicator from the eleventh to the' nineteenth, twenty-first to the twentyninth, twenty-sixth to the thirty-fourth, thirty-sixth to the "forty-fourth, fifty-first to the fty-nintln, sixty-first to the sixtyl ninth, seventy-first to .the seventy-nint seventy-sixth to the eightyfourth, eightyfirst to the eight`y-ninth and the eightysixth to the ninety-fourth hundredths of a revolution of, said indicator. numbers arev arranged in a reversed order similar to the numerals beneathA the iigure 100 and each group of numerals have in circular alinement therewith a 0, which when the parts are at home position appears be-j` neath the opening 561, as shown in Fig. 5.

Above the opening' 57 -through which the numerals on .the dollar change drum 59'appear are stamped the following figures: 100,

50, 20, 10, 5, and 2 which represent ydifferent amounts in dollars tendered. Theroups of numerals of the indicator 59 Whic appear below the above mentioned gures comprise zeros and numbers from 1 to 99, l to 49, 1 to 19, 1 to '9, 1 to 4, and 1 arranged in reverse order similar to the numerals-'on the centl vchange drum or indicator and adapted to be vdisplayed during the first ninety-mne, forty- 65 nine, nineteen, four and one onehundredths All of said` of a revolution respectively of the drum 59. Referring now to Fig.' 3, it will beseen that the gearing for actuating the dollar change indicator is ident-ical with that for operating the cent change drum, the ten tooth gear Wvheel- 36 being secured tothe sleeve 2() which also carries the back indicator 19 for the unit-s of dollars `and the pinion v52 secured to the outer end of the sleeve 34 towhich is attached the front and back indicators 33 and 35 for the tens of dollars. The large gear Wheel 48 driven by the dollar sale indicators is not connected directly to the dollar change indicator 59 by the sleeve 49 as is the case with the cent indicator 51, but is arrangedto drive said indicatorby the following described gearing: Meshing with the gear 48 driven bythe dollar sale indicators is a pinion 60 secured to one end Aof a transverse shaft 61, vvhich has also' attached to it, near its center, a similar pinion 62 that 'meshes with an idler 63 (see Figs, 1, 3 and 5), which is mounted in the upper end of an arm 64 that projects from one end of a i sleeve 65 surrounding the shaft 61, the other end of said sleeve being securedy rigidlylto the frame of the machine. The pinion 63 meshes with a. gear wheel 66 loosely mounted upon the shaft 50 and which mesh-es with a portion -67 of avdouble.pinion,..th`e other portion 68 of which engages teeth formed upon the inner circumference ofone of the side Walls of the dollar change drum 59. This gearing is so proportioned, thatthe movement of one vtooth of the lWheel 48 will revolve the 4dollar indicator drum 59 an equal distance. The above 'described double 'pinion is mounted upon 'a gear Wheel 69 near its periphery, the said, gear wheel being loosely mounted upon the-shaft 50 between the gear .wheel 66 and a disk 7 0. attachedto the inner end of the cent changeA druml. This disk 70 is providedc with a laterally projecting tooth 71 (see Figs. 1, 5, 7 and 8), which, when the drum 51 is at zero, engages with teeth of a gear 72, thelatter having attached thereto a gear l72a half its size .but having the same number of teeth which mesh With the teeth of Wheel69. Secured to the'opposite side of gear 72 o'r forming a part thereof and in vertical alinem'ent with the disk 70 isalocking 'disk 73 provided with a concave portion 74 which is arranged to .engage the periphery of t'he diskv70 after the -first movement of the latter .and thereby becomelocked; the disk 70 having a 'concave portion 74a to permit the movement of the disk 73.

- It will be seen from the above description;

that,- when the cent drumv lstarts to re-v volve, it will rotatethe gear 72 one tooth, the latter in turn rotating the gear Wheel 69 one'tooth through `means v of the gearv 72a. The wheel 69 is provided with two hundred teeth, so that rotating it' one tooth will revolve it @nativo-hundredth of a revolution, which movement through the planetary form of gearing A66, 67 and 68 will rotate the dollar drum one-hundredth of a revolution. lVlien the `cent and dollar drums are simultaneously operated by their'sale indicators, the gears G6 and 69 driven by the dollar and cent drum respectively will move in opposite directions whereby the dollar drinn 59,

through the above described planetary gearing, will bennoved an additional one-liiindredth of a revolution to that imparted to .it by its sale indicators, so as to properly indicate the change due.

Having now described the invention in detail a. rsum of its operation willbe given.

Assuming that all of the parts are at Zero and $5. has been tendered in payment for a. purchase amounting to $2.7 5, the clerk depresses the $2., .70 and .05 cent keys and turns the crank 6. during the movement of ivliichthesegments 2- corresponding to the banks in which keys are depressed will be connected to the 'rock-shaft 3 Vand move therewith -until disconnected by the depressed keys. Each'movement of the segments 2 will betransmitted to their respective indicators through gears 7; and through suitable shafts and pinions Athe back and front indicators of each denomination will move synchronously, all of which is well known in the art and fully described and shown in'tlie patent to Cleal and Reinhard heretofore mentioned. The cents indicator 9 (see Fig. 3 ),`will be given live-tenths of a revolution, and through the sleeve 1() rotate `the tentooth wheel a corresponding distance, which in turn will rotate the pinion 37 mounted in the outer end of the arm 3S, live teeth, the latter engaging with the gear wheel l1 formed upon the circumference ofv the angular rim 40 of the disk 39. The gear wheel 4l meshes with the portion at? of the double pinion, the other portion 13 of which meshes with the `ear wheel 4l formed upon the vinner circum erence of the disk t6; upon the outer circumference of which is formed the gear wheel 47 which meshes with a similar wheel 4S connected to the cent change indicator. The dimes indica-tor 13 is arranged to be given seven-tenths of a revolution by its segment and through means of .the sleeve 1Q (see Fig. 8), revolves a pinion 52 connected thereto a. similar distance. -It' the..dim'es indicator is-iotated' by itself, the pinion 52 .will be revolved. vin the direction of the arrow thereon (see 4F ig. 2), and through the pinion 53 carried by the arm 54 and internal gear wheel -la rotate the disk 55 and the 'arm 56 attached thereto in the direct-ion of arrow A the gear wheel 5l? being twice the size of pinion 52 will be rotated only half the distance` or seventWentie-ths of a revolution, but by the plane-` v reading tary gearing 41, 42 and 43 the disk t6 carrying the gears 44 and 47 will be rotated twice ion through the gear'fll formed upon the4 disk 89 any movement of said disk` in addi'- tion to the movement imparted to said pinion by the portion vQ riding over the teeth 41, These movements of the double pinion will be transmitted through gears 4l and 4T of the disk -16 and the gear 48 and sleeve et?) to the cent change drum 51. The gearing between the sale indicators 9 and 13 andthe change drum 51 is soproportioned that every tenth of a revolution of the cents indicator will revolve the cents' change drum one-liundredth of a revolution, while every tenth of a revolution of the dimes indicator will revolve the cents change drinn one-tenth of a revolution and the simultaneous operation ofthe sale indicators 9 and 13 will revolve the change drum 51 a number of `units corresponding to that displayed by the sale indicators.

' vIn the particular example chosen the -tens of dollars indicator remains at zero position but the units of dollars indicator is moved two .spaces and thereby through the gearing shown at the left of Fig. 1 and which is precisely similar to the gearing at the right of this ligure, transmits a two space movement to pinion 60. shaft (5l and pinion' 62. The operation of the cents and dimes mechaiiisni causes pin T1 to operate its connected .gears and'to move double pinion 6T, (3S one space. this'move'inent causing an additional movement of vthe dollar drum, so thatas a result of the direct movement of the dollar drum due to the dollar indicator and the transfer movement ot'said drinn. due

. 0 to the cents drum, said dollar drum is moved three spaces thereby indicating two dollars as-tlie correct change from the five dollars tendered. The movement of the cents drinn through seventy-live spaces will cause it to present the numeral at the line indi ating the fractional change due. Y

The operation, when amounts requiring the movement of the tens` of dollars indica-v tor are employed, will be obvious from the foregoing and need not be further elaborated.

It is to be understood that if a fraction, of a dollar is to b e taken out of any coin orbill over a dollar. itis always necessary to read the amount displayed upon: the cent drum 51 below the ligure 100 upon the casing, as Well as the amount exhibited below the figure upon the dollar section representing the amount tendered. in order to find out the correct amount of change;

As will be seen in Fig. 5 the numerals of the cent drum 51V which appear beneath the ligure lil() are of the same color as the nu lncrals upon the dollar drum 55, so as to aid in quickly locating the fractions of a dollar that are. to be returned in change.

A fact recognized by all merchants is, that, one of their greatest sources of loss is mistakes in change. Such mistakes would be reduced to a minimum with a machine ot' the class above described in use.

livhile the form of device here shown and t'lescribed is admirably adapted to fulfil the objects primarily stated, it is to be linderstood that. it not-desired to confine the invention to one form of embodiment here disclosed, for it is susceptible of embodiment in various forms, all coming within the scope of claiims Which follow.
